High Speed USB Serial Adapters Standard serial ports via USB 2.0 without replacing peripheral hardware or application software For over 20 years, Quatech has been KEY FEATURES known to help you Connect with Reliability. As we continue in the race to become the industry leader, our high 1, 2, 4 or 8 independent serial ports performance device connectivity line expands with the new high speed USB RS-232 or software-selectable 2.0 Serial Adapters. The next generation RS-232/422/485 Quatech USB Serial Adapter hits speeds of up to 921.6 kbps, 1024-byte FIFO and Compatible with USB 1.1 hardware and software flow control. Plug-and-play capability Quatech USB Serial Adapters enumerate themselves as standard COM ports that are compatible with all Devices enumerate themselves as Connect serial peripherals with USB standard RS-232 or RS-232/422/485 standard COM ports 2.0 Serial Adapters devices and software created for them. If speed, expansion and support are With the industrial surge suppression Speeds up to 921.6 kbps what youre looking for in a USB Serial IND option, you can safeguard the USB Adapter, think Quatech. Serial Adapter. The IND option is ideal High speed UARTs with 1KB FIFOs to for implementing USB-to-serial networks boost data rates in factories, power plants and other You can now broaden the range of potentially harsh industrial external peripherals used on your environments. USB 2.0 is fully Optional surge suppression package computer at higher speed rates than the compatible with USB 1.1 devices. The (standard on Embedded products) USB 1.1 series, with the introduction of older devices work with the new bus, the High Speed USB 2.0 Serial and vice versa. Full modem control and hardware and Adapters. The USB 2.0 has more software flow control bandwidth that allows higher data rates The 400 Series models introduce the on the serial ports for more efficiency. software-selectable RS-232/422/485 Bus powered: no external power required (Multi-Electrical Interface or MEI). The MEI capability is available on all ports at The new High Speed USB Serial Embedded (board-only) units also the click of a mouse.
